Multithreaded testing in the Testng

@Test (Invocationcount = ThreadPoolSize = 50)

@Test This annotation has two properties,

Invocationcount is setting the number of executions of this method
ThreadPoolSize This property represents the number of open threads

The setting of the threadpoolsize depends on the setting of the Invocationcount, if the Invocationcount setting value is less than the ThreadPoolSize set value, more than the setting is invalid, for an extreme example, If your ThreadPoolSize setting is 100 and Invocationcount is not set (the default is 1), then the system only runs with one thread open. The Invocationcount setting does not depend on threadpoolsize,testng to run with the default value.
